Resin Basics
- What is the difference between epoxy resin and UV resin?
Epoxy resin is a two-part system that cures chemically over hours, while UV resin is a one-part gel that hardens in minutes under ultraviolet light. They differ in working time, curing method, and best uses. - How do I measure and mix epoxy resin correctly?
Measure epoxy resin and hardener by weight or volume exactly as the manufacturer specifies, then mix slowly for 3–5 minutes, scraping the sides and bottom. Inaccurate ratios or poor mixing cause sticky or soft cured resin. - Why is my resin still sticky after curing?
Sticky resin usually means the resin and hardener were not mixed in the correct ratio, not mixed thoroughly, or cured in a too-cold environment. UV resin can stay tacky if not exposed to enough UV light or if the layer is too thick. - Can I use epoxy resin for small jewelry projects?
Yes, epoxy resin works well for small jewelry like pendants, earrings, and rings, but you need a casting or doming resin with a long working time and proper safety gear. UV resin is often easier for tiny pieces because it cures in minutes. - Is UV resin safe to use indoors?
UV resin can be used indoors with precautions: work in a well-ventilated area, avoid skin contact, and use a UV lamp designed for resin. Uncured resin can cause skin irritation, and fumes may bother sensitive people. - Should I wear gloves when working with resin?
Yes, you should always wear gloves when handling uncured resin. Epoxy and UV resins can cause skin irritation and allergic reactions, and gloves protect you from direct contact.
